If one of your auto-fill form sections is not working (i.e., not returning search results or not filling in the appropriate form fields) we recommend navigating to the form section and confirming that the form field and auto-fill source columns are mapped correctly. This can be done by clicking on a form field and then seeing what column in the source file it is pulling from. Once you click on a form field within an auto-fill form section, a menu will appear on the right side indicating what column from the source file is filling that specific form field. If the source file is empty, then there is no data mapped to that form field.
This article will provide more details regarding auto-fill form sections.
